Dear Mailing List, Is there are way to match packets specifying both network generation ip4 or ip6 together with the protocol such as tcp or udp? Currently the following rules are possible (examples): ipfw add 1 allow udp from any to me 22 in recv em0 ipfw add 1 allow ip4 from any to me 22 in recv em0 The following rule is not possible (example): ipfw add 1 allow ip4 udp from any to me 22 in recv em0 Is there a workaround for this or some reason why this hasn't been implemented? Or do I simply not have the rule syntax right. Regards, Dries
